GGU-GABION: Capabilities
The GGU-GABION program has the following special capabilities (and maximum values):
Almost any kind of definition of gabion bodies may be defined.
Base inclination of the gabion body
Up to 50 soil layers
Up to 40 berms on the active earth pressure side
Up to 40 berms on the passive earth pressure side
Analysis with active and increased active earth pressure and with at-rest earth pressure
Coefficients of active earth pressure pursuant to DIN 4085
Coefficients of passive earth pressure pursuant to DIN 4085, Streck, Caquot/Kerisel
Additional active and passive ep calculation to Culmann is possible
Analysis of settlements according to DIN 4019
Verification of external stability
Verification of inner stability to EC 2/DIN 1045-1 or DIN 4093
Verification of sliding safety, overturning safety and maximum geogrid forces
Convenient interface to the stability analysis application, GGU-STABILITY, for quick determination of safety factor against general failure
Seismic effects via additional horizontal loads and/or altered earth pressure coefficients
Analysis of static equilibrium in the EQU limit state
Analysis of pull-out resistance of geogrids via gamma(B)
Up to 50 additional earth pressure distributions
Up to 20 area loads at any depth
Structural analysis of the wall by means of a two-dimensional rod construction module based on finite-element methods
Specification of up to 5 displacement boundary conditions (rotation, displacement in x or y directions) at any location
Specification of up to 5 action boundary conditions (moment, shear force and normal force) at any location
A variety of different earth pressure redistribution figures:
no redistribution
rectangle
2 rectangles
triangle (maximum can be optionally placed at top, middle or bottom)
trapezoidal
quadrilateral with maximum at anchor locations or any other location
user-defined polygon
Passive earth pressure can be superimposed (global safety factor concept) or located in front of the wall.
Following computation of the system, earth pressure, water pressure, moment, horizontal force, vertical force and the relationship V·µ/H are automatically displayed on the screen. The visualisation can be varied within wide limits.
Display of the pressure line, the 1st and 2nd kernel width and the gravity axis
Legends can be displayed on screen indicating soil characteristics, general computation data, data needed for settlement calculations and the main design data. Thus, virtually all the raw data necessary for the computation are shown on screen.
GGU-GABION's user interface is based on WYSIWYG (What You See Is What You Get), which means that what you see on the screen is virtually identical with what is printed. It also means that you can print out what you see on the screen at any point during the analysis.
The use of true-type fonts guarantees excellent layout.
Colour presentation of virtually all system geometries. Colours can be freely determined by the user. In particular, soil strata can also be coloured according to the German DIN 4022 conventions.
Zoom function
By clicking the "Copy/print area" icon on the toolbar you can copy any part of the graphics to the clipboard or save it as an EMF file (Enhanced Metafile Format). Using the "Mini-CAD toolbar" or "Header toolbar" modules, you can paste emf files into your graphics. Thus, the results of a slope failure analysis or of a grading analysis, for example, can easily be imported into the current graphics.
